g This invention relates to improvements in soda fountains and its purpose is to provide an improved ice cream cabinet.

The principal object of the invention is a soda fountain comprising an ice cream cabinet'embodying improved heat insulat-.

ing means. A further object is to provide an ice cream cabinet having means for preventing passage of heat from the upper cap- 10. ping to the interior lining of the cabinet. In cooler boxes of the, form heretofore com monly used, the condensation and accumulation of. moisture on the cover of the box has resulted in a very disagreeable and unsanitary condition, a great loss of refrigeration and eificiency; it is an important object of this invention to overcome these defects. Other objects relate to various features of construction and arrangement which will 20. appear more fully hereinafter.

' The nature of the invention will be understood from the following specification taken with the accompan ing drawing in which one embodiment is il ustrated. In the drawings:

Fig. 1 shows an interior front elevation of a soda fountain embodying the features of the present invention. t

Fig; 2 shows a vertical section through an ice cream cabinet which constitutes the improvement of the present invention.

Fig. 3 shows a perspective view of the one-piece top or capping for the cooler box.

As illustrated in the drawings, the invention is shown in connection with a soda fountain 10 having a series of carbonated water and cold water faucets 11, and a series of'receptacles 12 adapted. to contain fruit juices and other flavors. The inner wall 13 40 of the series of receptacles 12is inclined u wardly from the cap ing 14 which-forms t 0 top of the cooler iiox 15. This cooler box is rovided with a series of receptacles closed y covers 16, t ese being adapted to contain crushed fruits or other materials, and in addition thereto the cooler box is provided with a pair of ice cream cabinets closed by covers 1'2, each cover having a removable lid 18. g

The top cover or capping 14 of the cooler box is stamped from a single sheet of metal, preferably nickel silver or other. suitable material; This one-piece capping is provided-viith a plurality ofopenings with eac 14, as shown in Fig. .3, adapted to permit access to the various receptacles for ice cream, crushed frult or the like. There maybe one or more ice cream cabinetsand a plurality of other receptacles as in the embodiment illustrated. One of the ice cream cabinets is illustrated particularly in Fig. 2 where-the in-- terior chamber 20 is shown as having a cylin dr1cal lining 21,. this lining being formed preferably of tinned copper or the like. A comparatively thick layer 22 of cork or other heat insulating material is provided around the lining 21- a nd the heat insulating material is enclosed by the outer walls 23 WhlCh are formed of marble or other suitable materlal. The cappin 14 has its edges bent downwardly around t e various openings 14 to form flanges extending around these openings, as illustrated particularly by the annular flange 24: extending around the opening to the ice cream cabinet in =Fig. 2. Each of these flan es is spaced inwardly from the metallic hning of the receptacle with which it is associated and the flan e is insulated from the lining by an interme iate layer of heat insulating material. In Fig. 2 the lining 21 is shown terminating below the top capping 14 and an annular band 25 of heat insulating fiber is shownmounted between the upper part of the linin and the annular flange 24 which extends ownwardly from the capping. This heat insulating material interposed between the ca ping and the several metallic linin s of tiie receptacles prevents the passage 0 heat to these linings and overcomes objectionable sweating and accumulation of moisture on the top surface of the cooler box.

The various covers and lids, 16, 17 and 18 which are used for closing the openings I 14 in the capping 14, are each formed by two sheets of metal which are spaced'apart to receive heat insulating material between 311cm. This construction in connection with e cover 17 and lids 18is illustrated particularly in Fig. 2-where each cover 17 is shown as compr sing two sheets 26 and 27\of nickel silver or other suitable metal-which are stem (1 in the proper shape to interfit other thusforming an inner eavity adapted to lie-filled with cork-or other heat insulating material- 28. The .outer' edges of the lower lates 27 are crimped, as shown at 29, to orm horizontal fiangfis" adapted to-rest on the upper surface of t e capping 14 around the opening to the ice y cream receptacle, and also to form an upwardly extending flange adapted to internt with thedownwardlyturned flanges 30 on the upper cover plate'26. vWhere the cover 17 is provided with an opening adapted to be closed by the lid 18, the inner edge of each lower plate 27 is turned upwardly to form an annular flange 31 adapted to interfit With the downwardlyturned flange 32; on the upper plate 26. Each upper plate providedwith an annular bead or rim 33 extending upwardly therefrom in proximity to p the flange 32 to prevent contamination of the ice cream by materials collecting on the upper surfaces of the cover and the capping l. The opening in each cover 17 is closed by the lid-18, previously referred to, which is circular inform and made up of two sheets 35 and 36 of nickel silver which are die stamped and telescoped together with the interior space filled by cork or other heat insulating material. The lower sheet 36 of when in use because of the fact that the parts are formed with very few joints or seams and are united without the use of rivets. 'The formation of the capping 14 in one piece is of particular advantage in facilitat- 1ng the cleaning of the cover of the cooler' box, and'the absence of joints in this capping serves in conjunction with the use of the flanges extending downwardly into the openings 14 to permit the various covers to fit closely .to the upper surface of the capping so that a tightrcontact is maintained and the loss of refrigeration prevented. A further feature of the construction of the capping is the provision of an integral ridge 38 which extends along the outer edge thereof, projecting above the top surface of the capping and having a flange 39 extending downward ly' in alignment with the outer vertical surface of the cooler box If desired, another integral ridge 40 may be provided along the inner edge of the capping.

The construction of the ice cream cabinet prevents the passage of heat from the top cover or cappingjof the cooler box to the interior lining of the ice cream receptacle thus preventing anyloss of refrigeration and overcoming any objectionable sweating or accumulation of moisture on the metal cover of the cooler box. The loss-"oat refrigeration by either conduct'ion or radiation is thus prevented by the construction of the cooler box and the lining.

one-piece construction of the capping cooperates with the absence of objectionable joints or seams in the covers and lids to provide a neat, attractive, and sanitary ap paratus forsoda fountain use.

Although I have shown and described one embodiment of the invention for purposes of illustration, it'will be understood that may be constructed in ivarious other forms without departing from the scope of .the-

appended claims.
